This one really blew my mind. Is this what natsocs actually believe? The very question of whether or not someone "deserves" the circumstances into which they are born into is absurd in an of itself.
This caller sounds EXACTLY like a communist, and his arguments are not new or unique from communists. Outside of cases of random luck, people who go from poverty to success are successful for a good reason. If someone climbs their way out of poverty that generally says something about the type of person they are and thus the type of children they would raise. So GENERALLY SPEAKING children inherit the merit of their parents, and thus in some sense deserve the circumstances they were born into. Even if you don't want to say they deserve it, then at the very least they are by definition most likely going to be the ones who would be most suited to preserving and managing the wealth their parents created. No one ever said an economically free society is going to result in a utopia, but trying to play god by redistributing wealth (either directly or indirectly through nationalization of various kinds of institutions, services, & resources) will only ever result in making things worse for everyone.
It's not really about what people deserve, more about whether or not they are likely to (on average) put the resources they were born into to good use. As culturally decayed as western society is, it's still true that on average successful people raise better children, you just don't hear about it as much because it doesn't suit the pro-wealth redistribution narrative.
